This ain't the 60's or 70's anymore
They will NOT get away with it anymore
That's not quite accurate. Most (though not all) of the "Winter Soldiers" Kerry cited were in the military, and most had been in Vietnam, but relatively few were in combat, and therefore few were in a position to see the atrocities they claimed were rampant. The trick they used was to recount horrible "war crimes" in gruesome detail, while remaining vague about who, what, where and when, thereby making it difficult for investigators to verify or disprove their accounts.
